TOXVING-HOOK FOE SHIPS AND THE LIKE.

Application filed July 17, 1912.

b all whom it may concern Be it known that I, BERNHARD \VILIIELM Pn'rnuTHIES, merchant, a subject of the German Emperor, residing atAltona-onthe-Elbe, Germany, have invented certain new and usefulImprovements in Towing- Hooks t'or Ships and the Like, of which thefollowing is a specification.

The present invention relates to a hook such as connected to ships orthe like for the reception of a towline and of the kind adapted to beturned so as to allow the line to slip oli'.

The invention consists in the construction and combination of parts ashereinat ter set forth and illustrated in the drawing, of which Figure 1represents a view of the hook in its operative position, and Fig. 2 aview 01 the same in releasing position.

The hook consists of a bar a to the outer -end of which a linger c ispivotally connected, the bar a being itself hinged to an eye Z) which issecured in any suitable manner to a tug or the like. The finger c ishinged at 7;- to a link (Z which has its opposite end hinged to abell-crank lever e, the latter being pivoted at i to the bar a. When thehook is in use the finger c is supported by means of the link J on thebell-crank lever which is in its turn supported, as shown in Fig. 1, ontwo links 7, and g of which one is pivoted to the lever and the other atj to the bar a. The links f, are so constructed that, when they abutagainst one another in supporting position, they have a tendency toyield and so to withdraw the support from the finger c. To retain thelinks in supporting position two flaps m, w. are hinged to the sideedges of the links one to each. These llaps are also hinged to oneanother by means of a hinge )in 0 dis iosed at ri ht angles to the )insI t i l which connect the flaps with the links.

When the flaps are folded against the sides of the links, as shown inFig. 1, the

hinge-pin 0 prevents the links from turning about their pivots. If theflaps, however, are turned up at right angles to the links, then thelatter can turn about the pin 0 as shown in 2, so as to release thetowline.

The pin 0 has an extension 79 which is bent at an angle thereto and soconnected to a cord 9' that a pull on the latter etlects a turning ofthe flaps for withdrawing the support from the finger c. \Vhen thesupport is thus withdrawn, the finger turns into the position shown inFig. 2, thus enabling the towline s to slip ott' along its tapering edge75.

An outwardly inclined lug u is provided on the bar a to retain thetowline within the hook.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is A towing hook consisting of a bar to which a finger ispivoted, said finger being supported, in a position to retain thetowline, by two pivoted links abutting against one another and tendingto turn so as to withdraw their support from the finger, the links beingretained in supporting position by two flaps which are. hinged to thesides of the links and to one another, the hinge connecting the twoflaps being setat right angles to the hinges connecting the flaps to thelinks so as to prevent the latter from turning except when the flaps areset in a plane at right angles to the plane in which the turningmovement takes place, the flaps being connected to a cord for turningthem into releasing position, substantially as set forth.

In testimony whereof, I atiix my signature in the presence of twowitnesses.
